WordPress 使用的数据库操作类就是它 — ezSQL
我用了好多年了，我特别喜欢它的几个类方法，可以有效提高代码简洁度。

下载 : 最好的 PHP DB 类 ezSQL 2010-04-13 (60.53 KB, 已下载 36 次)
新版本是2.05添加了很多支持，包括 CodeIgniter,MSSQL, PDO 等等
我之前也为 CodeIgniter 写过一次，不过只支持 MySQL
看看使用示例，详细的文档请看这里
其实也没什么难度，直接看源代码即可，主要是程序设计的思想很好。
Example 1
—————————————————-
// Select multiple records from the database and print them out..
$users = $db->get_results(“SELECT name, email FROM users”);
foreach ( $users as $user ) {
// Access data using object syntax
echo $user->name;
echo $user->email;
}
Example 2
—————————————————-
// Get one row from the database and print it out..
$user = $db->get_row(“SELECT name,email FROM users WHERE id = 2″);
echo $user->name;
echo $user->email;
Example 3
—————————————————-
// Get one variable from the database and print it out..
$var = $db->get_var(“SELECT count(*) FROM users”);
echo $var;
Example 4
—————————————————-
// Insert into the database
$db->query(“INSERT INTO users (id, name, email) VALUES (NULL,’justin’,'jv@foo.com’)”);
Example 5
—————————————————-
// Update the database
$db->query(“UPDATE users SET name = ‘Justin’ WHERE id = 2)”);
Example 6
—————————————————-
// Display last query and all associated results
$db->debug();
Example 7
—————————————————-
// Display the structure and contents of any result(s) .. or any variable
$results = $db->get_results(“SELECT name, email FROM users”);
$db->vardump($results);
Example 8
—————————————————-
// Get ‘one column’ (based on column index) and print it out..
$names = $db->get_col(“SELECT name,email FROM users”,0)
foreach ( $names as $name ) {
echo $name;
}
Example 9
—————————————————-
// Same as above ‘but quicker’
foreach ( $db->get_col(“SELECT name,email FROM users”,0) as $name ) {
echo $name;
}
Example 10
—————————————————-
// Map out the full schema of any given database and print it out..
$db->select(“my_database”);
foreach ( $db->get_col(“SHOW TABLES”,0) as $table_name ) {
$db->debug();
$db->get_results(“DESC $table_name”);
}
$db->debug();
